statement: -
This invention relates to a multiphase fullD wave rectifier assembly.
In our German Offenlegungsschrift No.
2,656,447, there is described, a multiphase, full-wave rectifier assembly, comprising a first plate, a second plate substantially parallel to the first plate, first and second sets of diodes carried by the first and second plates respectively, terminals of the first set of diodes extending through holes in the second plate, a connector electrically interconnecting said terminals of each diode of the first set with a respective diode of the second set, a support structure in the form of an electrically insulating body having recesses therein, a further set of diodes disposed respectively in said recesses, said recesses being shaped so as to hold the diodes of the further set in predetermined relative positions, one of the terminals of each diode of the first set being electrically connected with a respective one of the connectors, and a common connector connecting together the other terminals of the diodes of the further set.
In a specific example of such a rectifier assembly construction, we disclosed a two-part support structure comprising a first moulding having said recesses therein and an electrically insulating cover having portions overlying said recesses, said portions of the cover being shaped to prevent disengagement of the diodes of the further set from the recesses but to permit the terminals of the diodes of the first set to project from the body.
According to the present invention, there is provided a multiphase full wave rectifier assembly comprising a first set of diodes; a second set of diodes; a further set of diodes; each diode of the further set having a body and a terminal extending from each end of the body, a first plate carrying the diodes of the first gei.
a second plate which (a) is spaced from the first plate (b) carries the diodes of the second set and (c) has holes therethrough, terminals of the diodes of the first set extending through the holes in the second plate; a respective connector electrically interconnecting (a) said terminal of each diode of the first set, (b) a terminal of a respective diode of the second set, and (c) one of the terminals of a respective diode of the further set; a support structure in the form of an electrically insulating body having recesses therein, the body of each diode of the further set being disposed in a respective one of the recesses so that the diodes of the further set are held in predetermined relative positions; and a common electrical connector connecting together the other terminals of the diodes of the further set, said common electrical connector or said respective connectors being shaped so that portions thereof overlie said recesses in the electrically insulating body whereby the diodes of the further set are retained in said recesses by said portions of said common electrical connector or said respective connectors.
The above form of construction obviates the need to provide a separate electrically insulating cover such as the cover 127 disclosed in our German Offenlegungsschrift No 2,656,447.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig 1 is a plan view of a multiphase fullwave rectifier assembly according to one embodiment of the present invention, for mounting on a motor vehicle alternator, and Fig 2 is a section on the line 2-2 of Fig 1.
Referring to the drawing, the multiphase full-wave rectifier assembly illustrated therein is similar to that disclosed in our German Offenlegungsschrift No 2,656,447 and similar parts are accorded the same reference numerals.
Briefly, the assembly comprises a negative plate 101 carrying three power diodes (not shown), a positive plate 103 carrying another three power diodes 104, an electrically insulating body 105 carrying a further three diodes 106, which are field diodes, three metal connectors
2 1,599,898 2 107 and a common electrical connector 133.
The plates 101 and 103, and the body 105 are stacked one on top of the other so that the plates 101 and 103 are in spaced apart relationship Mounting bolts 200 and insulating bushes 201 (only one shown Fig 2) serve to maintain the plates 101 and 103 in spaced apart relationship and the bolts 200 also serve to secure the metal connectors 107 in position.
The metal connectors 107 electrically interconnect respective terminals 112, 117 and 129 of the diodes on the negative plate 101, the diodes 104 and the positive plate 103, and the diodes 106 carried by the body 105.
The other terminals of the diodes on the negative plate 101 are electrically connected therewith The other terminals of the diodes 104 are electrically connected with the positive plate 103 and the other terminals 129 of the diodes 106 are electrically connected with the common electrical connector 133 In the place of the electrically insulating cover 127 described in our German Offenlegungsschrift No 2,656,447, the common electrical connector 133 is provided with a generally Y-shaped portion 202 at one end thereof and a generally L-shaped portion 203, at the other end thereof, said portions 202 and 203 being integral with the remainder of the common connector 133 Each short limb of the Y-shaped portion 202 holds a respective one of the diodes 106 within a respective recess 128 in the electrically insulating body 105 Similarly, the shorter limb of the L-shaped portion 203 of the common connector 133 holds the remaining diode 106 in a corresponding recess 128 in the electrically insulating body 105 As will be apparent from Fig 2, the recesses 128 are of a shape such as to hold the terminals 129 in the diodes 106 in the required orientation Flexing of the Y-shaped portion 202 and L-shaped portion 203 is prevented by the provision of respective rivets 204 and 205 which serve to secure said portions 202 and 203 firmly against the body 105 in the region at which said portions 202 and 203 are joined with the remainder of the common connector 133 As can be seen particularly in Fig 2, the Yshaped portion 202 is cranked upwardly beyond the rivet 204 before being cranked downwardly to engage against the respective diodes 106 As can also be seen from Fig 2, the respective terminals 129 pass through plunged holes 210 formed in a part of the Y-shaped portion 202 which is spaced away from the body 105 The L-shaped portion 203 is similarly crankedSuch a cranked arrangement of the portions 202 and 203 permits the connections with the respective terminals 129 to be at the same level as the other connections to be made between the other terminals 129, 117 and 112 and the connectors 107 This enables all of the Lonnections to be soldered by means tit a flow soldering operation.
The above form of multiphase full-wave rectifier assembly is easier to assemble than the assembly described in our German Offenlegungsschrift No 2,656,447 and, like the latter assembly, serves to hold the field diodes 106 in the recesses 128 both prior and subsequent to the above-mentioned flow soldering operation, whereby, in service, the diodes 106 are firmly held against unwanted vibration.
Other advantages of the above-described rectifier assembly over that disclosed in our German Offenlegungsschrift No 2,656,447 are as follows:1 The whole assembly, and particularly the field diodes, operate at a lower temperature in view of improved access to heat generating parts by cooling air.
2 Because the field diodes are held by individual parts rather than trapped by a common part, the field diodes can be held more effectively in position This results in an improved performance in service because of the reduced risk of vibration of the field diodes.
3 Apart from being easier to assemble, the above-described assembly is cheaper because it uses less parts.
4 A greater flexibility of design is permitted.
In an alternative embodiment (not shown), instead of portions of the common electrical connector 133 overlying the recesses 128, as described above, to retain the diodes 106 in position, portions of the connectors 107 are arranged for this purpose.
